목적 : There has been no study on radiological changes in untreated blow-out fractures of the orbit. The purpose of our study was to determine if untreated blow-out fractures of the orbit undergo spontaneous improvement based on radiological findings using the following outcome measures 1) change in bony contour, 2) new bone formation, and 3) decrease in orbital volume.
방법 : Retrospective review of all patients with conservatively treated blow-out fractures of the orbit seen at Samsung Medical Center from 2012-2016 with initial and follow-up computer tomography (CT) scans.
결과 : Our study comprised 44 orbits. Majority were males (65.9%), and mean age was 34.3±13.5years. Median time of injury to follow-up scan was 6.5months. Most cases (n=42, 95.5%) showedradiological improvementon follow-up scan, of which 88.6% had joining of bony edges, 75.0% had reduction in orbital contentherniation and 86.4% had smoothening of orbital contour. 93.2% of patients showed features of neobone formation. Mean total orbital volume reduced from initial (28.9 mL) to follow-up (25.2 mL)CT, and fracture volume significantly reduced from 2.9 mL to 0.9 mL from initial to follow-up scans.
결론 : A large proportion of patients showed improvement in radiological findings despite being treated conservatively, with smoothening of bony contour, joining of bony edges, reduction in orbital content herniation, features of neobone formation and reduction in both total orbital and fracture volumes. This highlights that spontaneous improvement can occur in untreated orbital fractures not just clinically but radiologically as well.
